Like other northeastern Pacific Aldisa the body is covered with low conical tubercles. It differs in being completely white. Rhinophores and gills are the same color as the notum. Spicules can be seen within the tubercles.

Surprisingly this species feed on the red sponge, Hamigera. Adults reach 12-27 mm in length.
